I don't have an account yet so I can't access the ad wizard (my site is still in development and won't enter production for at least another month).

Visually speaking, is it possible to make my ads look exactly like that screenshot? In terms of the full width of the 3 ads combined, the width of each individual ad, as well as the spacing between each individual ad?

I reckon there won't be no problem changing the colors, as well as removing the underline from the main link.
